CRIMPING OR CORRUGATING MACHINE.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed October 21, 1914. Serial No. 867,877.

To all whom it may concern Be it known that we, WILLIAM S. Louonn and AnALoo M. ENGLISH, citizens of the United States, residing in Rochester and Brookline, counties of Strafford and Norfolk, in the States of New Hampshire and Massachusetts, respectively, have invented an 1mprovement in Crimping or Corrugating Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a crimping or corrugating machine, and is herein shown as embodied in a machine for crimping or corrugating the lip of an inner sole for boots and shoes, for which purpose it is particularly applicable.

The invention has for its object to provide a highly eiiicient machine for the purpose specified. To this end, the machine is provided with mechanism for crimping the lip, which has provision for forming a crimp or corrugation in the lip and for preventing distortion ofthe formed crimp or corrugation while a second crimp or corrugation is being formed.

Provision is also made for feeding the inner sole while the crimping mechanism is inactive, and for holding the inner sole sta tionary while the feed mechanism is disengaged from the inner sole.

Provision is made for'turning the lip into :r. substantially vertical or upright position, and also for limiting the height to which the lip can be turned.

Provision is also made for adjustment of the various parts of the machine as will be described.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a side elevation of a machine embodying thisinvention. Fig. 2, a front elevation of the machine shown in Fig. 1. Fig. 3, a rear elevation of the machine shown in Fig. 1 with parts omitted. Fig. 4:, a detail in section on an enlarged scale to illustrate the action of the crimping mechanism. Fig. 5, a detail in plan of the crimping mechanism, and Figs. 6 and 7, details of the anvil to be referred to.

Referring to the drawings 0: represents a stationary frame to support the operative parts, which latter consists essentially of.

mechanism for crimping the lip 7) of an inner sole 0, and mechanism for feeding the inner sole.

The crimping mechanism is preferably made as herein shown and consists of an abutment member, which will be hereinafter referred to as the anvil, and a plurality of tools cooperating. therewith, and which will be hereinafter referred to as the crimping tools. The anvil may and preferably will be made as herein shown and consists of an inclined foot 12 at the lower end of a bar or rod 10, said foot being provided on its upper surface in the present instance with two concavities 13, 14, see Fig. 6, into which portions of the lip b are forced by the crimping tools as will be described.

The anvil is vertically adjustable in a head 15 on the end of a lever 16, and is secured in its adjusted position by a pin 17 and nut 18 in a manner well understood. The lever 16 is pivotally mounted on a stud or pin 19 extended from the frame, and is connected by a link 21 to one arm 22 of a bell crank lever23, mounted on a stud or pin 24 extended from the frame a, and having its other arm 25 connected by a link 26 or otherwise to mechanism such as a foot treadle, not shown. for oscillating the lever 16 so as to move the anvil bar 10 into and out of its operative position.

The crimping tools which force the lip 6 into the concavities 13, 14, are and may be made as herein shown, and consist of two bars 26, 27. see Fig. 5, which are provided at their front ends with crimping projections or noses 28. 29, suitably shaped to force the lip 6 into the concavities 13, 14, in the anvil. The crimping bars or tools 26. 27, are movable toward and from the anvil and for this purpose, said crimping tools are movable with a carrier, which is herein shown as a lever 30. pivotally mounted at its rear end upon a stud or pin 31, carried by one arm 32 of a lever 33, pivoted at 34: to the frame a and having its other arm provided with a pin 86 on which is mounted a roller 37, which cooperates with a cam 38 on the rear face of a cam disk or wheel 39 fast on the front end of a main or driving" shaft 40,

mounted to turn in the frame a and prothereof, and the other 27 of whi'ch'is loosely fitted in said slot, and backed up by a spring t3 for a purpose as will be described. The "spring 43 bears against a laterally extended arm on the tool 27, to normally keep the said arm in engagement with the rear end --of the tool 26, see Fig. 5. The pressure'of the spring &3 may be adjusted or regulated by a screw 46extended through the rear end of the lever 30. The tool 27 and the spring 43, are retained in the slot 42 by a cap or yremovable cover 47, which is suitably sei cured to the lever 30.

' The crimping tools'26, 27,- are reciprocated toward and from the anvil 10 by the cam 38,

which oscillates the lever 33, and said tools 7 are guided in theirreciprocation by a guide,

herein shown as a lug or projection on the frame a, WhlClL projection is provided i with a slot or guideway through which the front-ends of said tools project.

The tool 27 is made longer than the tool 26, so that 'when the rear end of the movable tool 27 is in contact with the rear end-of the tool 26,

the nose or crimping projection 29 of the tool 27 will eXtend'beyondthe nose or crimping projection 28 of the tool 26, a suliicient "distance to insure that the nose 29 engages the last crimp formed in the lip 7), before the nose 28 pushes an uncrimped portion of the lip into the cavity 13 and against the anvil 10,-with the result, that a crimp which has been formed by the nose 28 on the forward stroke of the tool 26, will be engaged by the nose 29 and forced into thecavity 14 of the anvil and securely held by the nose 29 and anvil against movement, before the nose 28 forces the uncrimped portion of the lip 6 into the-cavity l3to formthe next adjacent crimp in the lip b. In this manner distortion of thepreviously formed CIlll'lP is prevented, and'the said crimp is held in its original or proper" shape, while the next ad acent or successive crimp 1s belng formed, and as a result, the hp 1) of an inner sole, which has been put through the machine is provided with regular or uniform and well defined crimps orcorrugations.

The nose 29 forcesthe previously formed crimp into'the cavityl' before the nose 28 forces the uncrimped portion of the lip 1) into the cavity 13, and to permit the nose 28 to be moved forward after the nose 29 has forced the previously formed crimp into the cavity 14 of the anvil, the crimping tool 27 is not fastened to the carrier 30 but is yieldingly backed up by the spring 43, so that, when the nose 28 is moved forward and forces the uncrimped portion of the lip into the cavity 13, the crimping tool 2" t is held stationary against the anvil by the spring 413, while the tool 26 and the carrier 30 are being moved forward with relation to the tool 27, and thus enable the nose 28 of the tool 26 to force the lip into the cavity 13 and form a crimp, while the previously formed crimp is held against distortion. by the tool 27. ()n the backward stroke of the crimping tool carrier, the spring 43 restores the tool 27 to its normal position in which it projects beyond the tool 26.

Provision is made for gripping the inner sole and holding it firmly while the lip Z) is being crimped, and for this purpose, the machine is provided with gripping mechanism which is arranged to grip the feather 51' of the inner sole.

The gripping mechanism may and preferably will be made as herein shown and consists of an upper jaw and a lower jaw 61. The upper jaw 60 is made as a metal block, which is located below the front portion of the crimping tools 26, 27 and is secured as by screws 62 between substantially horizontal. side arms 63 on the upper end of a lever or rocker arm 64-, attached to a hub 65, see Fig. 1, which is loosely mounted on a. shaft or pin 66, supported by lugs or cars 67 on the base 68 of the frainea. The lower jaw 61 is movable toward and from the upper jaw 60, and is formed by one arm of a bell crank lever 70. which is located between the arms 63 of the rocker arm 64- and is mounted loosely on the pivot pin 71, and has its other arm 72 extended downwardly and provided with a roller 73, which coiiperates with a second cam 74:, secured to the rear face of the cam disk or wheel 39. The lower jaw 61 is opened b the cam 7-1: and closed by a spring 7 5,.see" Fig. 4, which is'located in a socket in a boss 76 on the rocker arm 64-, and the tension or pressure of said spring may be regulated by a screw 77 and nut 78.

The cams 38, 7e are suitably shaped and arranged with relation to each other, to permit the crimping tools 26, 27, to be moved fornrd to crimp the lip I), while the inner sole is firmly held against movement by the i jaws 60, 61, and to permit the inner sole to be firmly held by the crimping tools 26, 27, and anvil 10, when the gripping jaws 60, 61, release the inner sole. Provision is made for feeding the inner sole forward after each crimp has been formed in the lip, and in the present instance the inner sole is fed forward by a path cam 80, see Fig. 2, in the front face of the cam disk 39, acting on a roller 81- carried by a stud 82 on the rocker arm or lever 6-1. The path cam 80 is suitably shaped and timed with relation to the cams 38, 741 and vice versa, to rock the lever or arm 6-1 forward or in the direction of the arrow 83, in F i g. 2, at or about the time the crimping tools are beginning their upward movement away from the anvil, and at or about the time the lever or arm 64. reaches the end of its forward movement in the digin their downward movement toward the anvil. When the inner sole is held by the crimping tools and anvil, the feed lever or arm 64: is moved backward by the path cam to bring the gripping jaws 60, 61, into position to again grasp the feather of the inner sole and effect the forward feed of the inner sole. When the feed lever 6% has reached the end of its forward movement, it is held stationary while the crimping tools are moved forward to enter the crimp last formed and to form a new crimp. tllhen the new crimp has been formed, the crimping tools are held stationary by the cam 38, and the cam 74: acts on the lever 7 2 to open the jaw 61 and disengage it from the feather of the inner sole, and at or about the time the jaw 61 is opened, the path cam 80 moves the feed lever backward into its starting position and at or about this time the cam 7 1 permits the spring to close the jaw 61 so as to grip the feather 51. At or about the time the feather 51 is gripped by the jaws 60, 61, the cam 38 permits a spring 90, see Fig. 3, to turn the lever 33, so as to move the crimping tools upwardly away from the anvil and thus release the lip b. The inner sole is now moved forward to bring the crimp last formed into line with the crimping nose 29 and the cavity 1 1, and an uncrimped portion of the lip into line with the nose 28 and cavity 13.

The crimping tools are now advanced toward the anvil,- so as to force the crimp last formed into the cavity 1 1, and to force an uncrimped portion of the lip into the cavity 13 to form a crimp, while the feed lever is stationary in its forward position. lVhen the lip is firmly held by the crimping tools and anvil, the cam 38 holds the crimping tools in this position, which allows the gripping jaw 61 to "open and the feed lever 61 to be moved back to its starting position.

Provision is made for opening up the lip, and for this purpose the fixed gripping jaw 60 is provided with a beveled upper surface 92, which forms with the flat under surface of the said jaw a substantially sharp or narrow edge 93, which extends into the channel between the feather 51 and the lip 72 in the substantially horizontal position of the latter. As the inner sole is fed forward, the beveled upper surface 92 separates the lip from the feather and turns the lip upwardly, and the extent to which the lip is turned is determined by a gage 94, which 1S secured to the frame a, and if desired can be made adjustable thereon in a manner well understood. The gage 9 1 is made as a metal block which is secured to the frame by a screw 95, see Fig. 2, and is provided in its bottom surface with a substantially V shaped recess or notch 96 for the reception of the edge of the upturned lip b.

In the machine herein shown, the anvil is moved into its operative position. by the operator depressing the foot treadle not shown, but which is connected with link 26, and is moved back into its inoperative position by the spring 98, or the reverse arrangement may be used.

The anvil bar 10 is capable of being ver tically adjusted with relation to the crimping tools to compensate for stock of different thickness, and the anvil is also capable of being adjusted laterally with relation to the crimping tools, which is effected by providing the frame a with a slot 100, see dotted lines Fig. 1, in which the pivot pin 19 is movable and has cooperating with it an adjustable stop in the form of a screw 101, which is extended into the front end of the slot 100 and is secured in its adjusted position by the nut 102. T he crimping tools 26, 27, are also capable of adjustment toward and from the anvil to compensate for lips of different thickness, and this adjustment is provided for in the present instance, by providing the cam lever 33 with an elongated slot 110, see dotted lines Fig. 1, through which the front end of the pivot pin 31 is extended, said end being threaded for engagement by a nut 112, which cooperates with a collar 113 fast on the pivot pin 31 to frictionally clamp the latter to the lever 33, see Figs. 1 and 5. The position of the pivot pin 31 in the slot 110 is determined by a set screw 114. which is extended into the rear end of the slot 110 through a threaded hole in the lever 33. To adjust the crimping tools toward or from the anvil, so as to comensate for lips of different thickness, the nut 112 and SCTQVVlll: are backed 0E, which leaves the pivot pin 31 and the carrier 30 free to be moved toward or from the anvil until the tools engage the lip, and when this takes place, the screw 11 1 is set up into engagement with the pivot pin 31, and the latter is then held from turning by a screw driver or other tool engaging a slot 116 in the end of the pivot pin, while the nut 112 is set up to clamp the pivot pin to the lever 33 by the collar 113 and the nut 112. lit is preferred to interpose a washer 117 between the lever 83 and nut 112. The machine may and preferably will be provided with'a suit- "able table or work support 120 which is shownassecured by screws 121 to the feed lever'64c.

We have hereinshown one construction of machine embodying this invention, but it is not desired to limit the invention to the par- .ticular construction shown.
